Abstract
An ophthalmologic apparatus, when an output result of an imaging unit provided in an optical path of an imaging optical system satisfies a predetermined condition, stops controlling a driving unit in at least one direction based on a positional relationship of an image of the light flux, which has been reflected by a cornea of the subject's eye and regulated by a light flux regulation unit provided in the optical path of the imaging optical system, and maintains the control of the driving unit in the other directions.
